It is rather primitive system which can now be a textbook example of the danger of inventing ad hoc languages.
In Linux complexity of PAM (over-complexity to be exact) exceeds the ability of regular administrators to understand it by large margin.
Please check out the sample code/project from the following Git Hub repository: https://github.com/svlada/springboot-security-jwt before going further reading the article.
This project is using H2 in-memory database to store sample user information.
This is especially true if you try to change something without understanding of complex interplay between modules (can we envision appearance "Linux PAM specialist" in job adds ? Also PAM include files is classic example of road to hell paved with good intensions: they provide additional capability for intruder to hijack access to the system in a way that is very difficult to detect.
Just try to answer the questions below for any Linux system: Converting this mess to a scripting language probably can improve things but it might be too late for linux with its pretty mature level of distributions and old age of OS itself.
The following topics are discussed: Usually, the application developer is responsible for designing the elements of an application, including the tables.
PAM permits modularization (plus some refactoring) of the old codebase.
For the past several days I have been focused on understanding the inner workings of several of the popular file synchronization tools with the purpose of finding useful forensics-related artifacts that may be left on a system as a result of using these tools.
Given the prevalence of Dropbox, I decided that it would be one of the first synchronization tools that I would analyze, and while working to better understand it I came across some interesting security related findings.
